Explanation:

Step1: Find dimensions of image

The preimage has length 9 and width 5. With scale factor 3, image length: \( 9\times3 = 27 \), image width: \( 5\times3 = 15 \).

Step2: Calculate image area

Area of rectangle is length × width. So, \( 27\times15 = 405 \, \text{u}^2 \).

Answer:

\( 405 \, \text{u}^2 \) (corresponding to the option "405 u²")
